Indeed. I believe it is even documented somewhere.

Two realistic solutions and an experimental one:

* use a "logfile monitor" (we use SEC
<URL:http://kodu.neti.ee/~risto/sec>) with a regexp of "nsd.*notify
from" and an action of "nsdc update".

* use cron to recompile every hour or less (ns2.nic.fr receives one
NOTIFY every ten minutes, there is not really any point in waiting for
them, we just recompile periodically).

* (Untested) see what's new in NSD 1.2 (just released). May be there
is a notify-handler plugin?
